Some people do not deserve help. Some people continuously make bad decision. I've seen such people turn their life around - but only after every friend gave up giving them free beds and meals. These people got straight A's in school until they figured out they could cheat society to get everything for nothing.
The problem is that is a tiny minority of homeless. Most homeless either are trying but things are set against them, or don't have the ability to fix their problems. Bay area housing is horribly expensive, and so there are a lot of homeless who would like to have a house but they can't afford anything on the income they can earn (long term the solution is fix zoning so cheap housing can be built, but best case this is 20 years to make a difference). There are a lot of disabled people who cannot work a good job - often the disability is mental, and thus they will never be able get a good job and support themselves.
How do we turn the "folks standing around in a welfare line" conversations to reminding people that those exist but are a minority and most homeless have problems that we should help them with? don't attack the message of lazy people - it is a real issue, just reminding people that we are looking at those who are not lazy.
